Panasonic WhisperComfort Spot Energy Recovery Ventilator (ERV) offers a revolutionary way to provide balanced ventilation with a ceiling insert ERV. Affordable and easy to install, WhisperComfort is energy efficient and provides fresh ventilated air while maintaining indoor air quality. ADDITIONAL BENEFITS • Totally enclosed motor for long life –rated for continuous run • Rust-proof paint treatment on galvanized housing • Mechanical supply air damper employed • Dual setting air volume for 40/20 or 20/10 CFM • Supply and exhausted air filters employed • One motor operates two fan wheels • Uses two 4-inch ducts INSTALLATION Mounting WhisperComfort measures 14 inches wide and fits between joists 16" on center. Brackets and screws are provided to secure the unit to the joists on 4 corners. Wiring Power consumption is 23 Watts at 40 CFM with a power rating of 120/60 V/Hz. Bring house power to the unit junction box and use 3 wire to connect the 2 switches. Duct Insulated 4" duct is recommended. For cold climates, insulated duct running through a cold attic will help avoid condensation build up. And for warm climates, insulated duct running through a hot attic will help reduce heat transfer to supply air. In all cases, in order to reduce unnecessary airflow resistance, duct should be stretched straight and braced to avoid sagging. Assure that all duct connections are completely secured with zip ties or duct straps and sealed with duct tape and/or duct mastic material. Elbows Rule number one is to avoid elbows and bends whenever possible. However, the fact is that many installations may require at least one elbow. There are two precautions to take when installing elbows to achieve optimum performance. First, allow a 2 – 3 foot straight run out of the unit before the first elbow. This allows for air flow momentum before passing through the first elbow. An installation that has a 90-degree elbow immediately after the exhaust port will cause air to back flow into the unit. This will reduce fan performance and may increase noise. Second, use a long radius angle (not a tight short radius) to help ensure optimum airflow and minimum airflow noise. Termination/Supply Device The exhaust termination device (roof cap or wall hood) may have a back draft damper. The supply device will need to have the back draft damper removed and replaced with a screen to prevent insects and small animals from nesting. The termination and supply devices should be placed a minimum of 3 feet apart. If placed closer than 3-feet, then the angle of each device should be mounted at 45-degrees in opposite directions. MAINTENANCE (Cleaning) Maintenance instructions can be found in the Operating Manual. Grille The grille can be washed with light dish soap. Follow the Operating Manual and remove the grille from the unit. Next, remove the filter from the inside louver of the grille. Never use gasoline, benzene, thinner or any other chemicals when cleaning the grille or ERV unit. Do not wash in dishwasher, which may be too hot and cause grille to deform. Use light dish soap in the sink. Filters WhisperComfort has two air filters. One filter is located on the inside louver of the grille. The second filter is located in the unit held by a bracket with a handle.

Frost Prevention Mode WhisperComfort incorporates built-in frost prevention technology to prevent exchange core freeze-up. • Above 32ºF both exhaust and supply are fully functional • From 32ºF to 20ºF the mechanical damper on the supply air closes for 30 minutes, then opens 1 hour at the set high/ low mode. The cycle repeats itself to avoid core freeze-up. (Exhaust-only 30 minutes per 90-minute cycle) • Below 20ºF the mechanical damper on the supply air remains closed for 1 hour and opens 10 minutes at low mode. After 10 minutes the cycle will repeat or change if the temperature has risen above 20ºF. (Exhaust only 60 minutes per 80-minute cycle) Settings WhisperComfort has two 2-speed CFM settings High Low __________________________________________________ Setting 1. 20 CFM 10 CFM Setting 2. 40 CFM 20 CFM factory preset The factory setting is 40/20 CFM. To change to optional 20/10 CFM setting, move the plug connector located in the junction box to the 20 CFM side of receptacle. This step must be completed prior to installation. Switches WhisperComfort operates in an on/off and high/low mode. When switch is turned off, the unit does not operate. When switch is turned on the unit will operate at the high or low mode. A duplex switch, designed for a single gang box. may be selected for switch operation. Switch labels are provided for convenience to attach to the selected switches. 32ºF Open 1 hr. Close 30 m.

Whole House Ventilation (IAQ) Balanced Ventilation With Spot ERV WINTER SUMMER Outside Inside single room. The unit provides a low rate of continuous air exchange. Fresh air is supplied while maintaining balanced air pressure. This is an affordable way to add ERV to a specific room or a new addition. Ideal for: Home office / Game rooms / Family rooms Whole House ERV WhisperComfort may also be suitable to meet whole house ventilations requirements under ASHRAE 62.2. The sizing charts on the next page provide a guideline for number of bedrooms and square feet. Additionally, two or even three WhisperComfort ERV’s may be installed, often at a cost lower than a traditional whole house ERV. Ideal for: Condominiums / Housing Authority properties / Hotels / Studio Apartments ASHRAE 62.2 2007 Standard The American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) set a standard for whole house ventilation, requiring that continuous mechanical ventilation be 7.5 CFM per bedroom (master bedroom X 2) plus 1 CFM per 100 square feet, with sone level not to exceed 1.0. Panasonic WhisperComfort ERV is an affordable, efficient way to meet this ventilation standard. Spot ERV Ceiling Insert Ventilator FV-04VE1 4" x 2 Ducts FEATURES Balanced Ventilation Tightly built homes and buildings minimize passive air leaks. An exhaust-only fan may create negative pressure. Whisper- Comfort solves this by supplying air to replace exhausted air, helping to balance air pressure within the home. Panasonic WhisperComfort spot ERV uses two 4 inch ducts – one to exhaust stale air and the other to supply fresh air from outdoors. Its low rate, continuous run ensures chemi- cals such as volatile organic compounds (VOC’s) and other pollutants from cleaning fluids and building materials are vented out and replaced with fresh air. Exchange Capillary Core Indoor and outdoor air passes through Panasonic’s capillary core technology designed to transfer heat energy and moisture. This process tempers supply air while transfer- ring moisture. Motor Technology Panasonic uses a single AC condenser motor to run two highly efficient blower wheels. The motor is totally enclosed to ensure long-life and continuous quiet operation. Filters Two filters clean exhaust and supply air before passing through the ERV core, extending the life of the core.
